METHOD FOR SYNTHESIZING NANOPARTICLES ON SURFACES

摘要

A method of forming a nanostructure on a substrate surface can include heating a substrate comprising a composition comprising a block copolymer and a nanostructure precursor to a temperature above the glass transition temperature of the block copolymer and below the decomposition temperature of the block copolymer to aggregate the nanostructure precursor to form a nanostructure precursor aggregated composition. The method can further include heating the nanostructure precursor aggregated composition to a temperature above the decomposition temperature of the nanostructure precursor to decompose the polymer and form the nanostructure.

1. A method for forming a structure on a substrate surface, comprising:
contacting a substrate with a tip coated with a composition comprising a block copolymer and a structure precursor to form a printed feature comprising the block copolymer and the structure precursor on the substrate; heating the printed feature to a temperature below a decomposition temperature of the block copolymer to aggregate the structure precursor and form a structure precursor aggregated printed feature; and heating the structure precursor aggregated printed feature to a temperature above the decomposition temperature of the structure precursor to decompose the polymer, thereby forming the structure.
